IMPROVEMENT IN PHOTOGRAPH-BURNISHERS.

Specification forming part of Letters Patent No. 168,457, dated October5, 1875; application filed August 14, 1875.

To all whom it may concern:

Be it known that I, JOHN COUMBE, of Rhinebeck, in the county of Dutchessand State of New York, have invented a new and valuable Improvement inPhotograph Burnishers; and I do hereby declare that the following is afull, clear, and exact description of the construction and operation ofthe same, reference being had to the annexed drawings making a part ofthis specification, and to the letters and figures of reference markedthereon.

Figure 1 of the drawings is a representation of a transverse verticalsection of my photograph-bnrnisher, and Fig. 2 is an end view of thesame. Fig. 3 is a front view thereof, and Fig. 4 is a plan view of theheatingapron.

This invention has relation to photograph burnishers and it consists,mainly, in the construction and novel arrangement of the large upperiron roller,having a roughened surface, the smaller polished steelroller below, having an upward motion in suitable ways, the me tallicheating-jacket and its roller-bearings, arranged under the lower rollerand over the lamp, and the screw-adjusting frame, all as hereinafterfully shown and described.

In the accompanying drawings, the letter A designates the frame of themachine, having the supporting-legs B, lamp-shelf O, and rollstandardsD, provided with bearings a for the journals of the large roll, and withslots b for the journals of the small roll. E represents the large roll.the cylindrical surface of which is roughened by longitudinal creases orgrooves, in order to give it a purchase on the card-back of thephotograph, which is designed to be introduced between said large rolland the smaller roll. This smaller roll F is made of polished steel, incylindrical form. Its jonrnals revolve in the blocks 0, which slide upand down in the slots b of the frame, and are supported on thescale-beam joints 0 on the lever n, by means of which the height of theroller is adjusted. Blocks 0 in railgrooves bear on the journals of thelower roller. Springs 8 may be placed between said blocks 0 and theupper ends of the slots. These rolls are geared to move in the samedirectionthat is, their adjacent surfaces will move in oppositedirections when the large roll is turned by means of its crank G. Themode of gearing which I prefer is illustrated in the drawings. The smallroll is provided with a large gear, f, and the large roll with a smallgear, 6, said gears engaging with a third gear, g, which is supportedand connected to the journals of said rolls by angular springs s, havingloops 6 at the ends and in the bends for the gear-journals. The upwardmovement of the lower roll will not afl'ect the engagement of the gears.H represents the metallic heating apron or guard. This consists of aconcave semi-cylindrical central portion, K, in close, proximity to theunder surface of the lower roll F, and the heat directing and conductingflanges 1 depending therefrom in a downward and outward direction oneach side of said central portion. Thisguard may be readily bent up outof sheet metal. At its ends bearings m are attached, to rest upon thebranches or arms a of the press-lever M. This lever extends transverselyof the frame, being pivoted at the points 1, and the ends of its arms nare joined by a broad bar, a, under which is located a pressing-screw,V, whereby said lever may be raised or lowered, according torequirement. I designates the lamp, which is placed under the guard orapron.

This is a compressing and polishing burnisher. The lamp having beenlighted, and the proper degree of pressure between the rollers havingbeen secured, by moving the screw V, to raise the arms of the lever, theapron, and the lower roll, the card is introduced between the rolls facedownward.

What I claim, and desire to secure by Let ters Patent, is-

1. In combination with the lower roll of a photograph-burnisher, theadjustable flanged heat-apron and the adjustinglever, substantially asspecified.

2. A photograplrburnisher having the upper large roughened roll E, thelower adj ustable and smaller polished steel roll F, having,respectively, large and small gears engaged to rotate in the samedirection, the flanged heat-apron H, the compressinglever M, and itsscrew V, substantially as specified.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.
